Third option
RNA polymerase binds to DNA at a region called as promoter. The sequence of promoter is highly conserved in prokaryotes and eukaryotes. This enzyme that scans the DNA and begins transcription at transcription start site.
Translation is initiated at start codon by the enzyme peptidyl synthase. Messenger RNA is bound by ribosomes which scans the DNA to look for start codon. The process than ends at stop codon.

1. Which of the following statements concerning transcription of bacterial mRNA is not true? Bacterial mRNA must have intron material removed before it can be used in the process of protein translation.* Energy necessary for transcription is provided by the breaking of phosphate bonds carried by ribonucleotide triphosphates (rNTPs). A sigma factor recognizes the promoter site sequences on the DNA strand during transcription. A guanine-rich sequence on the template DNA molecule causes the growing RNA strand to loop and detach.
